VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 556,355, dated March1'7, 1896.

Application led March 24, 1893. Serial No. 467,46 7. (No model.)

To all whom t may concern:

Be it known that we, JOHN A. LANNERT and WILLIAM R. JEAvoNs, citizens ofthe United States, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improvements inVapor-Burners; and we do hereby declare that the following is a full,elear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

Our invention consists in a novel arrangement of the parts for initiallyheating the burner, and also in means whereby two or more burners aresupplied from one vaporjet orifice, together with other novel featuresof construction and combination as shown and described and particularlypointed out in the claims.

In the accompanying drawings, Figure lis a vertical central elevation ofthe generator. Fig. 2 is a plan view of a section of the induction endof the mixing-chamber and shows the ducts or openings to supply airthereto. Fig. 3 is a plan view of astove embodying our improvenients andhaving the top broken away to disclose the burner mechanism beneath, as

hereinafter more fully described. Fig. 4is a section on line y2 2, Fig.3, showing the closing and regulating plate over the burner in positionto deflect vapor into the lighting-duct above the mixing-chamber. Fig. 5is a crosssection on line 3 3, Fig. 3, showing the relation of thelighting-duet to the mixing-charnber and the depth and constructionthereof.

In the drawings like letters of reference designate like parts in allthe figures.

A is the supply-pipe for the oil or vapor, and forms a continuation ofthe supply-pipe from the oil-tank and serves alike for all the burners.A duct a a from the upper part of the supply-pipe communicates with thevalve or needle oriiice a', which is controlled by the valve a2 having astem convenient for the operator.

C is a chamber in which the vapor and entrained air are thoroughlymixed, and is designated as the mixing or eommingling chamber.

D is a duet from the bottom of the mixingchamber to a receptacle Eformed about the base of the upright supply-pipe A and serves,

when initially starting the burner, to conduct the gasoline escapingfrom orifice a to the said receptacle E. This receptacle E is in theform of a deep circular trough or its equivalent and extends around thebase of the upright supply-pipe A.

F is a valve controlling an oriiice f at the upper end of the duct f,which communi- Gates below with the supply-pipe at its lower end andserves to discharge gasoline or oil into the receptacle Il. The troughor receptacle Eis iilled with some absorbent material, such as asbestosor the like, and both the duct D and valve-orifice f are in position todischarge near the top of the troughE and a little below the surface ofsaid absorbent material, for reasons hereinafter described.

A perforated tube G is seated on the sides of trough or receptacle E andextends upward and surrounds the pipe A at some distance from it toleave a name-space between it and the said pipe A.

The mixing-chamber C extends across to all the burners, and at the topthereof are flanged openings c c c. In these openings are perforatedburner-plates c', which seat in the openings a little below the outeriiange c2, as shown in Fig. 4. A hat plate H is pivoted at one side ofthe burner and lies iiat upon the flange c2, thus effectually closingthe burneropening c. By sliding the said plate laterally more or less anopening of greater orless size is made for the escape of gas from thechamber C.

A duct, gutter or channel I extends from one burner-opening to anotherover the mixing-chamber C, as shown in Fig. 5. This channel or duetserves as a path for vapor to travel in andignite one burner fromanother, thus facilitating the transfer of ignited vapor from one burnerto another.

The plate H is formed with a groove or hollow h on its bottom at oneside, so that when the said plate is moved to uncover a portion of theopening c, as shown in Fig. 4, the opposite side of the plate overlapsand directs gas into the channel, which, by reason of its gravity, flowsalong the channel to the next burner-opening.

J J are small perforations through which gas escapes in jets when theburner is in operation and burns about the generator op- ICO posite theopenings to maintain the burner at a vaporizing condition. Y

In operation, the burner-opening c nearest the generator being opened bysliding away the covering-plate II ,the valve a is opened and gasolineescapes from jetbrifice a through the induction-tube B into chamber C,the walls of which chamber are so constructed as to conduct the gasolineto duct D, whence it runs to the absorbent material in initialstarting-trough E. A lighted match or taper is applied to or through asuitable lighting-hole near the base of the perforated tube G about pipeA, and by reason of the vapor evolved from the light hydrocarbon thusintroduced the flame will be immediately communicated to the gasoline atthe surface of the absorbent material in trough E, and ignitioninstantly follows. A blue flame will then fill the chamber formed by theperforated tube G and heat the ducts a a and upper part of the supply-pipe. These parts quickly attain to a vaporizing condition, andvapor then issues from the orifice a', and, passing through theinducting-tube B, entrains air in the usual manner. The vapor and airthoroughly mixing in said chamber C escapes at the unobstructedburner-opening near the generator in a commingled state, but forconvenience of this description and claims will be spoken of as vapor,and is ignited by the iire from the perforated tube, which remainsburning until all the gasoline that is drained into the absorbent isconsumed. lVhen it is desired to ignite t-he gas at the next burner thecover II to that burner is opened a little way, as shown in Fig. 3. Thisplaces the hollow portion of the cover in such relation as to directsome of the escaping gas into the duct or gutter I toward the ignitedburner. rlhe gas being heavier than air it will travel by gravity in thechannel to the ignited burner, and flame will flash over and passthrough the narrow space between the cover and the burnerplate and willbe communicated to the escap ing gas at the other side of the plate. Thespace between the perforated burner-plate and the regulating-cover IIwill admit of flame communication but is too small to admit of continuedcombustion therein.

By reason of the absorbent material in the trough E soaking and holdingthe gasoline from the sides of the trough the combustion is more gradualand does not increase to an annoying extent as the walls of the troughbecome hot. Again, by having the gasoline discharge into the trough nearits top the gasoline is quickly manifested at the surface of theabsorbent and consequently is ready for ignition at once.

The valve F may be opened to produce and l maintain a small iire to keepthe vaporizing portions in a heated condition over periods in which theoperation of the burner is not desired, and in this way the burner maybe kept ready for full operation at any time. If desired, the burner maybe initially heated as well as maintained in a heated condition by meansof this valve by simply opening the valve to a desired point andigniting the asbestos.

The manner of conducting air to the induction-tube B by the lateralduets l) D protects the gasoline or vapor escaping from valve-orifice afrom the flame that issues from the tube G, and some such protectionmight be considered an essential to this form of burner.

The burner-plate herein referred to may have any suitable shape or form,whether it be as here shown or in the form of a cone or any otherequivalent construction.

The plate or cover II opera-tes practically as a valve to control flowof vapor from a burner to the duct I, and is so considered and referredto herein. The flame area of the burner also is controlled by said coveror valve,as the cover may be more or less opened, as preferred.
